Lab-Grown Diamond Engagement Ring

When light catches the curves of a heart-shaped diamond, it reveals a tender silhouette that feels both intimate and bold. This semi-set solitaire invites you to choose a centerpiece that will become a personal emblem of love.

Crafted in warm 18K yellow gold, the mounting is shaped by hand in our Williamsburg studio, where each prong is carefully formed to cradle a 10 x 10 mm heart diamond securely. The band’s subtle taper and smooth finish ensure a comfortable fit, designed for everyday wear without catching or shifting.

Our commitment to lab-grown diamonds means this ring carries a clarity and brilliance born from sustainable innovation, reflecting a modern approach to ethical jewelry.

The low-profile setting suits those who favor understated elegance, while the solitaire style offers versatility—ideal for stacking with wedding bands or wearing solo as a statement of devotion.

Should you need resizing or prefer a custom finish, our Brooklyn studio offers personalized consultations to bring your vision to life with care and precision.
